You need to post pictures of this bike! It is a 1960 model sportsman. They were available in both footpeg and floorboard/crashbar models. Does yours have an internal or external kickstarter? I think they could be had in both low rise and high rise handlebars.
Picture 1 is a 1960 high handlebar with external kickstart.
Pictures 2and 3 is 1960 low bars and internal kickstart.
Picture 4 is a 1959 rear footpeg model. According to one source, this was 1959 only, but I have one, frame # 17956, that seems to indicate a 1960.
Picture 5 is a 1958 front footpeg sportsman. These had the standard fenders and wheels.
